Two-Loop Corrections to Top-Antitop Production at Hadron Colliders

Two-loop electroweak corrections to Higgs production at hadron colliders

We compute the two-loop electroweak corrections due to the top quark to the gluon fusion production cross section of an intermediate-mass Higgs boson. This result, together with the previously known contribution due to the light fermions, allows a complete determination of the two-loop electroweak corrections to this production cross section. For Higgs mass values above 120 GeV the top correcti...

Stop production at hadron colliders

Stop particles are expected to be the lightest squarks in supersymmetric theories and the search for these particles is an important experimental task. We therefore present the cross sections for the production processes pp̄/pp → t̃1t1 and t̃2t2 at Tevatron and LHC energies in next-to-leading order supersymmetric QCD. The corrections stabilize the theoretical predictions for the cross sections, an...

Bilepton Production at Hadron Colliders

We examine, as model-independently as possible, the production of bileptons at hadron colliders. When a particular model is necessary or useful, we choose the 3-3-1 model. We consider a variety of processes: qq̄ → Y Y −−, ud̄ → Y Y −, ūd → Y Y −−, qq̄ → Y ++e−e−, qq̄ → φ++φ−−, ud̄ → φ++φ−, and ūd → φ+φ−−, where Y and φ are vector and scalar bileptons, respectively. Given the present low-energy const...

Higgs production plus two jets at hadron colliders

In this talk we present a calculation of Higgs production via gluon fusion in association with two jets, including the full top-quark mass dependence, and compare it to the large top-mass limit. We find that the large top-mass limit is a good approximation as long as the Higgs mass is smaller than the top quark pair mass, and the jet transverse energies are smaller than the top mass. In additio...
